Storage Card Issue

I had a 4g microsdhc card in the xv6800. Verizon btw.
Had a couple larger programs installed to the storage card.
Decided to upgrade a bit and got 8g microsdhc. Turned off
ppc, copied 4g's files to laptop, then copied to 8g.
Tried using Garmin gps, problem with that as I assume card id
has changed. Couple other card id generated serials did not want
to work either.
So I remove everything from storage, cept for some personal files
etc... And in the process of removing I came up with the brilliant
idea, hmm... new storage card, might as well try out the hard reset
feature and start fresh.
At the beginning everything was fine. I restored pim data with Sprite,
and when I installed Sprite, I installed to the storage card. Install went fine
but after the soft reset, its got default icon, and don't work. So I am thinking, ok, maybe its gotta be installed to the device. Yep that worked.
So I installed some other apps I thought should also go to the device, and they worked as well.
Came to some larger apps, Garmin first, and it works. But it's the only one
that works when I install to the storage card. Any app I have tried to install
to the storage card, after soft reset, has default icon, and won't open.
I searched thru the storage card, win folder, programs folder, my documents just in case, and they are all empty. and yes I am browsing with show all files checked.
Soz its prolly something real simple that I am overlooking. All I know is the
programs that I had installed to the storage card i assume aren't actually installing, cause there are no files, but same program will install to the device
and run/work.
Any takers want to point out my stupidity for me? What I doing/did wrong?
I really have NO clue what the problem is,
BUT,
I had an odd problem with files lost on my 4G card. I stuck it into a good card reader and plugged it into my laptop. I did a 'chkdsk' on it (checked it for errors) and it found a number of lost clusters. I let it repair those, and all was well.
Actually, I believe that when I saw the errors, I copied everything off the card and just reformatted it.
Don't forget the 'safe to remove' button on the PC.
thank ya very much.
done and done and working now.
formatted it using disc management in xp.
all good now.
thanks for pointing out my stupidity.
i forgot this is windows, when in doubt...format. lol

Post-root USB errors, anyone?

I finally got around to rooting mine earlier today..
Ever since, I can't get either of my computers (both Mac and PC) to recognize the phone for mounting the SD card. It charges fine via USB but is impossible to mount as USB storage. Any ideas on this?
Maybe a driver issue?
I thought that originally. But if that were the case, I wouldn't have been able to connect to them previously (no changes in drivers on the computers) or been able to connect to complete the root process. I'm kind of at a loss for ideas right now.
hmm strange... I'm a android newbie so i don't think i can help passed driver
Method?

Hey what method did you use to root? If you can mount your internal storage but not your sdcard, can your phone read your sd card when the phone is booted normally? Perhaps you damaged your slot?

exactly what i was thinking, but myz06vette are you able to view content from your sd card using just your phone? ex: music, movies or pictures?
Yes, I can view content on my SD card and internal phone storage on the phone itself using Root Explorer or ASTRO. I didn't use the method that required me to pull the SD card out. I can play music stored on the card and view all my photos, so I know its reading okay. I even took the SD card out and put it in a memory card reader and it hooked up to the computer fine.. mounted right away. Just won't mount through the phone.

The development.apk packaged in many Dream/G1 ROMs has an option to scan for media. Try that
BTW, *#*#4636#*#* also works from the dialer to pull up phone/radio options, which will allow you to switch between cdma auto (PRL) --> cdma only -->> ev-do only. The latter two options should save you battery!
Thanks for the advice! I updated to CDMA-only right when I got the phone.. so I honestly can't say whether or not its saving me battery since I don't know what it was like set to CDMA auto PRL hahaa.
I tried installing the Dev Tools apk you attached, but each time I do, it says "Application not installed" with the yellow !triangle next to it.

Sorry, man -- that .apk was from an Eclair build -- try the new one I put up -- it's from an Espresso build, I just installed in on my DI -- all good
Hah alright fair enough. This one loaded fine.
Checking it out now... will report back. Thanks!
Half of the options in the app force close.
Media scanner loaded, but isn't helping me mount the sd card to my computer.
Any more ideas?

So you've checked your settings in "Connect to PC" -- perhaps your "always ask" option is cleared and it's set to HTC Sync, for example? What do you get in the SDcard/Storage menu? Any stats for the SDcard? What happens when you elect to eject it in that menu?
Storage menu shows total space and free space like it should.
Connect to PC is currently set to Ask me everytime.. option for Disk Drive selected just to try and force it to mount..
Removed SD card.. did battery pull reset.. still nothing.

That's frustrating. You might have to back-up your sdcard data on a PC and re-format the card, then copy the data back. I'm assuming you have a card reader.
I hadn't thought until just now to try another card. I've got a few sitting around here somewhere. I'll try that before taking the time to backup almost a full 16 gigs of stuff, format, then restore it all.

Do you have some sort of app killer/task manager auto killing the obex service? Ive noticed i have problems when it isnt running, but when it is running it kills battery like mad. Try going to settings>applications>running services and see if its running next time you try to mount. It should show up under calendar. Hope this helps.
P.S. I only let this service run when i need to plug into my pc, since it seems to keep the phone from being able to "sleep" properly. So if you have something killing it, or the calendar app has been removed that may have a part in your problem.

Any else having problems with Internal Storage?

I seem to be having problems with the internal phone storage "Media Area." That's where the apps are moved when moving them to the SD Card. So all the time my phone loses contact with the media area and those apps are no longer available. I have to reboot my phone 3-4 times before they are accessible again.
Am I the only one having this problem? I've tried to unmount that partition but it just hangs and needs to FC. I'm wondering if I got a lemon and need to return it.

Mine just became in-accessible the other day, I just moved astuff from the internal to the sd while on USB mode.
Had to format. Wouldn't mount or anything & I think I was getting a "Internal Storage Defect" message. Works ok after the format..
I thought I was the only one. If I connect my Atrix to my macbook then umount it it's not accessible to the phone. I only have to reboot once though.

Same here. Everytime it mounts the SD cards on my Mac it forgets the custom ringtones. Annoying! Going to have to get the Wifi add-on for iSyncr!!!

I actually use Browsix now until the problem is resolved. I'm writing down each of my custom ringtones now that I am running the beta to see if it is resolved. Let you guys know in a few through an edit to this post.
EDIT: From preliminary testing so far seems to resolve the issue of failure to remount storage.
With Safely removing hardware: Ringtones Are remounted properly with no issue, internal storage has no issue. will test with external storage later but so far looking positive
With just yanking out the USB cable without safely removing hardware: You might have to manually remount internal storage but ringtones are restored properly. Internal storage can be remounted with the Settings Storage option.

Thanks! I should have known better than to just unplug without safely removing but I usually don't do it on my tablet and it doesn't cause a problem..but after testing that's exactly what it was
sort of the same issue...
my problem is that the downloaded ringtones show up but the default ringtones like the att tone etc. dont show even though i can use root explorer to navigate to them and play them. Any ideas on what i could do to fix this? Im rooted on 1.5.7 and want to stay away from a full hard reset if possible. Thanks for the help for this n00b in advance.

[WARNING] Beware of camera issues and SD cards sudden wiping

I want to warn you all that, the latest CM10, build 15th August, includes a wiping bug which can wipe your SD cards pictures and videos when it crashes after taking 2 photos (1 photo -> look in gallery -> return to camera and take it -> crash). It will wipe anything you've got, and I also seem to have an issue with getting su rights in terminal emulator, will try adb later.
What happened (external SD):
I took a picture earlier today, the Gallery app crashed. I come now to the laptop to backup my photos, and I connect my phone in CM10 (it's as 2nd ROM, don't you dare to come at me and say "hurr durr kernal not supported and dual boot too" because it's NOT kernel related.
So, I connect my phone, and I see all my folders tripled. DCIM 3x, Music 3x, .antutu 3x, and so on. I'm like "OK, I'm going to wipe the doubles, and all is going to be fine). I erase .antutu folder 1 is OK, folder 2 tells me I lost connection with the phone and folder 3 seems to be the original. I proceed to .estrongs, but I stop there.
I go with Solid Explorer, and I check out what's happening. There are NO tripled folders. I decided to reboot and boot into my primary ROM, CM9. Boot is fine, but I reach gallery, and I see my pictures vanish one by one, and I see that they're being deleted automatically. I have no idea how that can be possible, it was definitely some sort of wipe command from within. As I said, I can't get a logcat right now, and last_kmsg isn't going to help because it's not kernel related.
I now check again on the SD card, 32GB Samsung class 10 SD card, and I see that everything's wiped inside the DCIM folder. Camera, 100ANDRO, and my own personal folder, SC. Everything's gone. Wiped, and deleted, out of nowhere. I have no idea how to retrieve, because it has been wiped and there is no return now.
This is just a warning to you guys using CM10 last build, so hopefully you won't lose the ~500 pictures like me
hey man, plug your sd card to the computer and use recuva, it worked for me when i lost some dead space savegames

Issue is, I'm not home right now and I don't have any microSD adapters near me... All i can do is plug in the phone as USB mass storage and go from there.

You have to be on latest CM10 nightly (15th August) to get Mass Storage.
And thanks a BUNCH! It recovered some pictures, thank God I didn't take many in the last few days....
I am on latest nightly, but nothing happens if I change the Mass Storage option in ExTweaks, any other solution ?

Same Problem, How did you fix it?
Well if that isn't working you could try airdroid app. Maybe the cable is bad or going bad. Try to not move the phone or cable after the computer sees it.
